• It is an opportunity to celebrate the importance of postal services in facilitating communication, commerce, and connectivity between people and businesses across the globe.
• The Universal Postal Union (UPU), a specialised agency of the United Nations that coordinates international postal services, plays a significant role in promoting and organising World Post Day.
• The theme of World Post Day for this year 2023 is “Together for trust: Collaborating for a safe and connected future”.
